question

A charged cloud system produces an electric field in the air near Earth's surface. A particle of charge −2.0×10−9C-2.0 \times 10^{-9} \mathrm{C} is acted on by a downward electrostatic force of $3.0 \times 10^{-6} \mathrm{~N}$ when placed in this field. What is the magnitude of the electric field?
